Despite the recent reports on transition-metal catalyzed cycloisomerization strategies toward helicenes, the amount of palladium catalyzed routes remains rather scarce. Within this letter the successful preparation and characterization of novel dioxa-aza[7]helicenes using palladium mediated coupling reactions is presented.
尽管最近有关于过渡金属催化的环异构化策略用于螺旋芳烃的报道，但钯催化的方法仍然相当稀少。在这封信中，我们成功地使用钯介导的偶联反应制备和表征了新型的二氧杂氮杂[7]螺旋芳烃。
